LIQUiD-ME'AsUnING DEVICE.

Application led July 5, 1924. Serial No. 724,387.

To all whom t may concern.'

Be it known that I, WILLIAM F. Mownx, a citizen of the United States,residing at Attleboro, in the county of Bristol and State ofMassachusetts, have invented certain new and useful Improvements 'inLiquid-Measuring Devices, of which the following is a specication.

This invention relates to an improved construction of li uid-measuringdevice for storage receptac es such as those used for motor vehicles;and has for its object to provide in such a device an auxiliary tankthrough which fluid is passed into the storage receptacle, and to mounta bladed wheel or other suitable, rotatable member in the outlet`passageway of the tank to be rotated by fiuid passing through it intothe storage receptacle, also to provide a uantity indicator which isoperated by t e wheel for showing the amount of liquid which passes thewheel on its way into the receptacle.

'A further object of this invention is to provide a cover or closuremember for the quantity indicator and means for locking or sealing theclosure memberl so as to prevent inspection by unauthorized persons.

` The inventioif further consists in the provision of a float for movinga detent into and out of position to control the action of the measuringwheel and to mount this float in a casing or cylinder to prevent thesame from bein tampered with.

A still urther object of the invention is the provision of an air ventto permit air pressure to escape freely from theauxiliary tank so as toprevent air pressure in the tank from operatin the measuring wheel.

With these and ot er objects in view, the invention consists of certainnovel features of construction, as will be more fully described, andparticularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a side elevation Showing a storage receptacle for gasolineand the like and a receiving tank r mechanism housing member throughwhich the liquid is passed into the storage receptacle, the tank havingmeans affixed thereto for indicating the amount of liquid passed throughthe tank.

Figure 2 is a sectional side elevation of my im roved auxiliary tank.

gigure 3 is an end elevation showing the tank as partly broken away toillustrate the action of the mechanism mounted therein. Figure 4 .is aview showing the counting or indicating mechanism and the train ot gearsby which this indicating mechanism is actuated by rotation of the liquidoperated It is found in the operation of motor vehicles, particularlythe truck type which consumes large quantities of gasoline, of advantageto be able to check up the drivers report as to the amount of gasolinepaid for, and to provide a device through which the liquid is passedinto the storage receptacle, so constructed that its measuring mechanismcannot be tampered with, and also to provide an indicator or counterwhich will accuratelyshow the amount of liquid which has vpassed throughit and also to provide means for concealin this counter so that a driveror unauthorized 'person cannot see what the counter is registering, andtherefore, he has no'ineans for checking up his report and only theowner or an authorized person .can inspect the counter to determinewhether or not the report turned in by the driver is correct; and thefollowing is a detailed description of one construction of mechanism bywhich this result may be accomplished Vith reference to the drawings, 10designates the main, or storage receptacle which is carried by thevehicle and 11 shows the receiving tank through which the gasoline mustbe passed in order to fill the main' or storage receptacle. Thisreceiving tank is soldered, locked or otherwise fixed onto the neck 12of the main receptacle 10 and this auxiliary tank is provided with afilling neck 13 preferably set olf Ito one side of the central axisthrough the tank and is provided with a closure cap 14. Y

In the neck of this opening is mounted a screen 15 which is alsosoldered or otherwise fixed in position.

Intermediate the inlet neck 13 and outlet neck 16, I have formed anoutlet passageway 17 between the downwardly inclined plates A and Bwhich passageway is positioned preferably on the opposite side of thevertical axis of the tank,- to that of the inlet neck 13, or out ofalignment with this measuring mechanism, the plate A forming `adeflecting plate beneath'the neck 13 and having its edge adjacent thepassage 17. Below this passageway,'I have mounted a bladed or bucketedwheel 18 on a shaft 19 to 'rotate in a portion .of the cylinder `20,whereby the .'luid flowing `into the storage receptacle acts upon theblades of this wheel and rotates the same in the direction of the arrow,and on this shaft 19 which extends out through the walls 21 and which islrecessed and supported on bearing screws 22, one of whichis mounted ina bracket 23 and the other in the end wall 43 of the 'cylinder wherebythese screws maybe adjusted to position the wheel in its cylinder andto,

take up wear on the bearing of the wheel shaft 19. v

In order that the rotations of this wheel shaft may be counted, I havemounted an indicator or counter 24 on a bracket 25 on the outside wallof the tank 11 and this in-A.

,` shaft 19 are indicated on the dial-s `29, as

shown in Figure 4.

AThis wheel cylinder 20, as shown, is a unitary structure and the partscarried -by it may all be assembled before the cylinder is positioned inits casin and may be removed bodily therefrom or inspection and repairs.

In order to control the rotations of this measuring wheel, I havemounted a float 30 lin the cylinder 31. This float is connected to adetent pin 32the end 33 of which normally extends into position toengage one of the blades -18 of the measuring wheel and when xa smallportion of liquid is poured into the tank sufficient to raise the levelsuiiiciently to raise the float '30, this float will then lift thedetent and permit the free rotation of the wheel as the gasoline iows`through the tank into the storage receptacle. To relieve air pressurewithin the tank and prevent the operation of the measuring devicetherebv, I provide the large opening 34 in the side of cylinder 31, thevent holes 35 in the top of the cylinder and hole 36 in the end of theupwardlyprojecting neck and also the holes 37 in the protecting casing38, which casing is riveted orlocked so as to prevent tampering with thetloat. f It will also be noted that the cylinder 31, overhangs theoutlet passageway" 17 so as to prevent any instrument from beinginserted into the inlet neck to tamper with the wheel.

It is found of importance in my improved device to provide a cover 39for the counter or indicator 24, which is hinged at 40 at its upper endand the hinged portion being on the top of the casing, while at thelower end it has an opening which passes over the riveted staple 41through which is a lock 42 adapted to be sealed against being unlockedby unauthorized persons.

By my improved construction of liquid measuring device, I can preventfraud by being able to readily detect padded accounts for gasolinetrying to show amounts not actually u sed.

The foregoing description is directed solely towards the constructionillustrated, but I desire it to be understood that I reserve theprivilege of resorting to all the mechanical changes to which the deviceis susceptible, the invention being defined and limited only`by theterms of the appended claims.
